I am not against notching the tunnels as it looks cool.   I don't thinkthey notch stone work tunnels as it would weaken them.  We would haveto do something to change to concrete style or raise the ones we have.

The tunnel idea has merit...I am not sure but all of the UP (ex WP) areconcrete entrances between Sunol and Niles in the canyon.

That is true.   However, most of our tunnel portals are stone type.   Iam not so sure in reality could notch a stone tunnel with a keystone inthe center.   Maybe we could flll the stone work with plaster andconvert them to concrete style and notch them.

      Folks

Niles Canyon UP tunnels have the stack train "notch" in them. You cansee them if you look closely driving the highway between  Sunol andNiles.

        Hi Dean:

I have in the past run a string of two 5-unit sets of Maerskdouble-stack cars, with my Maersk lettered Santa Fe GP60M, and didn'thave any problems, with them, but it was a short train.  In the futureI was planning on running a longer train of various stack cars, andagree with you, that something should be done to the tunnel portals. "Notches" perhaps, like the prototype does.  In fact, just like theSanta Fe did on Techeapi Pass for the SP.

Members,

I was out at the club yesterday setting up a double stack train that I 
have been working on for quite some time.  I got a whole string of cars 
set up at Oildale (passenger track, Peter was running on the freight 
side), put some power on the front and headed towards the port.

Coming out of the tunnel, by Grainger, it was noted that there was very 
little clearance between the top of the stacks and the tunnel portal.  
Clearance would have been better if I was on the freight side.

Ran around the back and snagged a wire about a 1/3rd of the way along 
Hidden.   Fixed that and continued the run under the city.   Didn't 
check clearance at the other side, but no problems occured..

1. Problem #1, tunnel portal not tall enough to clear stacks at 
Jamestown.  Most missed, but one caught.   Put the train back together, 
backed it down, switched over to the passenger track and continued up 
the layout.   Still just barely cleared.

2. Problem #2.   First tunnel entering summit seemed ok.  Middle tunnels 
seemed ok.   Tunnel exiting Summit not ok on either end.  Something 
caught, midway, and string lined half the train.   Front half was 
catching on bridge or just barely clearing.

3.  Problem #3.  Tunnel exiting the helix just barely clears.  That was 
as far as we got with the train.  By then, most cars were off the layout 
and back in boxes.

We need some serious tunnel work if we want to run stack cars, and  I 
think we should do it.

Jere ran stacks on the Sunday of the train show and it appeared they 
made it around without problems.  Go figure.

Dean
